Background: This analysis was conducted to evaluate the efficacy and safety of temozolomide based chemotherapy in treating patients with glioma. Methods: Clinical studies evaluating the efficacy and safety of temozolomide based regimens for patients with glioma were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: In temozolomide based regimens, 5 clinical studies including 152 patients with advanced glioma were considered eligible for inclusion. Four clinical studies included temozolomide. Systematic analysis suggested that, in all patients, pooled CR was 21% (32/152), and PR was 21% (32/152). Grade 3/4 toxicity included neutropenia, thrombocytopenia, and anemia. No grade 3 or 4 renal or liver toxicity was observed. No treatment related death occurred with temozolomide based treatment. Conclusion: This systematic analysis suggests that temozolomide based regimens are associated with mild response rate and acceptable toxicity for treatment of glioma patients.

Liver fibrosis is caused by metabolic problems such as cholestasis, genetic problems, or viral infections. Inhibiting hepatic stellate cell (HSC) activation or inducing selective apoptosis of activated HSCs is used as a treatment strategy for liver fibrosis. It has been reported that when HSCs are activated, their apoptosis sensitivity to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is enhanced because the expression of death receptor 5 is elevated. Finding a natural compound that can enhance the apoptotic effect of TRAIL on HSCs is a necessary strategy for liver fibrosis treatment. It was confirmed here that mangosteen-derived gartanin increased the effect of TRAIL-induced apoptosis by increasing the expression of DR5 in a p38-dependent manner in the hepatic stellate cell line LX-2. Combined treatment with gartanin and TRAIL accelerated DNA cleavage through caspase-3 activation and enhanced antifibrotic effects in LX-2 cells.

Inoculation of primary pepper leaves with an avirulent strain of Xanthomonas campestris pv. vesicatoria induced systemic acquired resistance (SAR) in secondary leaves. This SAR response was accompanied by the systemic expression of defense-related genes, a systemic microoxidative burst generating H2O2, and the systemic induction of ion-leakage and callose deposition in the non-inoculated, secondary leaves. Some defense-related genes encoding PR-1, chitinase, peroxidase, PR10, thionin, defensin and zinc-finger protein were distiilctly induced in the systemic leaves. The systemically striking accumulation of H$_2$O$_2$and strong increase in peroxidase activity in pepper was suggested to contribute to the triggering of cell death In the systemic micro-HRs, leading to the induction of SAR. Treatment of non-inoculated, secondary leaves with diphenylene iodinium (DPI), an inhibitor of the oxidative burst, substantially reduced the induction of some defense-related genes and subsequently SAR.

Prostate cancer is the second leading cause of cancer death of men in western countries and the death related to this disease in Korea is also getting increased. Although anatomic imaging tools such as transrectal US or MRI have been playing a great role in detection of primary prostate lesion, the evaluation of regional lymph node or distant organ metastasis using these modalities is not successful. $^{18}F-FDG-PET$ scan is emerging diagnostic tool for various malignancies. Considering the usual characteristics of prostate cancer such as slow growing and osteoblastic metastasis, the application of FDG PET scan to this disease might be limited. However, in advanced prostate cancer refractory to chemotherapy, FDG PET scan show strong FDG uptake and SUV changes in serial PET scan can be a good indicator of treatment response. Although FDG PET can be useful only in limited cases of prostate cancer, its indication can be widened in future owing to rapid technical improvement and accumulated experiences in this field.

In this study, we examined the effect of luteolin to enhance TRAIL-induced anticancer effect in SK-Hep1 cells. We found that combined use of TRAIL with luteolin markedly enhanced the cytotoxicity compared to either agent alone by inducing apoptosis. Furthermore, combined treatment of TRAIL with luteolin significantly induced activation of death receptor pathway-related proteins as well as PARP-cleavage and activation of effector caspases. Also, our result indicated that upregulation of DR4 and DR5 by luteolin combination may contribute to enhanced susceptibility of SK-Hep1 cells to TRAIL.

Open pelvic fractures are rare, but pose challenges for trauma surgeons due to their high morbidity and mortality. Generally, early death results from uncontrolled exsanguination and late death is related to pelvic sepsis. Therefore, management of these injuries should prioritize hemostasis and contamination control starting in the initial phase of treatment. We report two cases of unstable open pelvic fractures with perineal wounds that were managed successfully.

Aortic dissection is an uncommon, life-threatening medical emergency that is associated with a high mortality rate, and death from aortic dissection is mainly related to secondary complications, namely cardiac tamponade, severe aortic regurgitation, acute myocardial infarction, and abdominal organ vessel obstruction. Hence, prompt and accurate diagnosis followed by proper treatment is important for patient survival. Herein, we present a rare case of sudden death after aortic dissection with concomitant acute myocardial infarction and cardiac tamponade.

Purpose: To investigate clinical outcomes of synchronous head and neck and esophageal cancer (SHNEC). Materials and Methods: We retrospectively reviewed 27 SHNEC patients treated with curative intent at a single institution. The treatment modality for individual cases was usually determined on a case by case basis. Results: The median follow-up duration for the surviving patients was 28.2 months. The most common site of head and neck cancer was hypopharyngeal carcinoma (n = 21, 77.7%). The lower esophagus was the most common location of esophageal carcinoma (n = 16, 59.3%). The 2-year progression-free survival (PFS) and overall survival (OS) rates were 57.5% and 39.6%. Major pattern of failure was locoregional recurrence in the study patients. Esophageal cancer stage, the Eastern Cooperative Oncology Group (ECOG) performance status, and pretreatment weight loss were significant prognostic factors for OS in univariate analysis. Treatment-related death was observed in two patients, and one patient developed a grade 4 late treatment-related complication. Conclusion: Although the survival outcome for SHNEC is poor, long-term survival might be achievable with aggressive treatment with stage I-II esophageal cancer and good performance.

DA-3585 is a recombinant human erythropoietin produced by Dong-A pharmaceutical Co. Ltd. using recombinant DNA technique. Recently, recombinant human erythropoietin (rHu-EPO) has been used to treat various types of anemia. In this study, we examined acute and subacute toxicity of DA-3585 in rats. DA-3585 was intravenously administered to rats at dose levels of 0, 6,250, 12,500 and 25,000 lU/kg for single dose toxicity study and at dose levels of 0,100,500 and 2,500IU/kg daily for 4 week-repeated dose toxicity study. In the single dose toxicity study, there were no death, clinical signs and changes in body weight gain related to the treatment. Necropsy revealed no evidence of toxicity related to DA-3585, In the repeated dose toxicity study, all the rats survived throughout the study. There were no treatment-related changes in clinical signs, food and water intake, and body weight. Hematological examination showed increases in the number of erythrocytes, hemoglobin concentration, hematocrit value and mean corpuscular volume, and decrease in the number of platelet in 500 and 2,500 lU/kg dosed groups. Extramedullary hematopoiesis in the spleen and erythroid hyperplasia in the bone marrow were noted as treatment-related histological changes. Toxicologically significant changes were not observed in blood biochemistry, urinalysis, organ weights and in any other examinations. The treatment-related changes observed in this study were hematological or histological changes associated with pharmacological effects of DA-3585. On the basis of the results of this study, LD5n value of DA-3585 was above 25,000 lU/kg and the no-observed-adverse-effect-level was estimated to be 100 lU/kg.
